CAR-UNDERFRAME Application filed January 4,

Specification of Letters Patent.

Patented Aug. 11, 1908. 190s. seria N b. 409,325.

-icatioir My invention relates particularly to the end-sill of a metallic car underframe as applied to that class of car known as blind-h lend, or without platforms, and has for its objectto provide a strong, rigid, and durable end-sill, having the butiing sill or mem'- ber integral therewith, and specially designed to resist abnormal shock and to transmit the ,stress thereon uniformly through the longitudinal sills of the underframe.

It consists in features of novelty as hereinafter'described and claimed, reference be ing had to the accom anying drawing froming part of this speci ication, whereon,

Figure 1, is a top plan view of my improved, end-sill; Fig. 2, a front elevation thereof, and Figs. 3, 4, and 5, ver-tical transverse sections through the sill'on lines 3, 3, 4, 4, and 5, 5, respectively, in Fig. 1.

Like letters and numerals of reference de note like parts in all the figures.

e represents my im proved end-sill which is preferably, composed of caststeel integral portion b (representing the' ordinary buiiing sill), which is preferably, box-shaped in cross section closed at each end, and having a middle .forward extension 1 of reduced depth; and a rear portionb (representing the endsill proper) which is preferably of an inverted L-shape in cross section formed by the rear wall 2 of the front portion b and the rearwardly extended portion 3 of the top wall of :front portion combined with reinforcing upright' transverse ribs 3', which unite the walls 2 and 3 together at suitable intervals along the same.

To the outside of each closed end of the rear portion b', which preferably extends `beyond and curves rearward from the rear wall 2 of the front portion b, is ixed laterally the end portion of the corresponding side longitudinal sill or member 4 (indicated by `dotted lirios) of the underframe, and from the middle of the rear portion b projects rearwardly a pocket c which is adapted to lcontain the bulling spring 5, with the followers 6 and 7 having the intermediate spring plates 8, and operated by the butiing stem 9 (all as indicated by dotted lines) whichis adapted to play horizontally throu h the openings 10 therefor through the en -sill c,'

and coupled in front to the chaling-plate 11, which cooperates with the buiiing stem 12 and springs 13 at each side of the middle bulling stein 9 in the usual well-known Inanner, the butfing stem 12 passing through Y openings 14 therefor in the end-sill a, and the springs 13 having their housing 15 formed in the rear portion b as shown, or in any other convenient manner,

To the upright side walls 16 of the pocket c, which preferably unite with the walls of and extend below the front and rear portions I). and b', are fixed laterally the end portions of the middle longitudinal sills. o-r members 17 of the underframe, and on the side and middle longitudinal sills or members 4 and 17 are fixed the floor-plates of the car frame, the end plate 1S at, and adjacent to its' outer edge, overlying the top wall Sfvof the rear portion b ofthe end-sill e, and secured thereto by-rivets (not shown) which pass through the holes 19 therefor in the top wall 3.

Projecting from the top of the rear portion b for its entire length, or thereabout, adjacent to the holes 19, is an upright web or flange 20 to which is fixed the upright end members (not shown) of the car-body, and which strengthens the rear vportion b of the end-sill a thereat, the flange 20 also forming an abutment to the said edge of the floorplate 1S. l

From the rear wall 2 of the front portion b depends an L-shaped bracket d which is integral with, and preferably extends laterally beyond the side walls 16 of the pocket c, the bracket d having two opposite bottom lugs 21 between which, to the underside/of the bracket d, is fixed the carry-iron 22- (indicated by dotted lines broken away) for thel cou ler-shank.

T Irough the top wall of the front portionV ired laterally to s, ila-nge 25 r. "werd from the top of the iront port Y ond integral therewith, the brrr 2t 'oen 'combined prefere-bly, with tWo 5 auxiliary opiigl'it bers 2t) fixed laterallyT to :in intermediate lug or llnnge 2T projet-ting 'upward from the top of the reni' portion o imriiedialtb; behind the opening; 23 the bers 2o bi: et their lower ends on the top of the roer mortier) t and et their iront edges seeinst t ie bar fiel, whereby strong` end rigid ottsehment ot the bers 24 and 26, or equivalent members to the end-sill o, and n eorrespomling resist-snee of the vestibule riliftphrogm treme to undue stress are insured. From the bottom of the front portion Il project lugs to which nreooupled the ele rises 29 lor the safety nnehor chains t no t sliown).

In the above e mstruetion, by making the ont portion or boiling still l) integral with ie rear portion or end-sill proper, com- `..e\.'l. with themiddlo extension l ol the "ront portion greatly increased strength r-d 'rigidity of the end-sillft for resisting .se stress is obtained. Moreover,
